What quarter is worth $2000?

Excuse me, but I'm a bit confused about something. Could you please clarify for me? The paragraph mentions a quarter being worth $2000, but I'm not sure I understand what that means. Is this referring to a specific type of quarter, perhaps a rare coin or a collectible? Or is there some other context in which a quarter can be valued at such a high amount? I'm genuinely curious and would appreciate any insight you could provide.
